Make it possible to set the local ports used for the non-secure (QEMU_NW_PORT) and secure (QEMU_SW_PORT) terminal when running QEMU.
When you need to run multiple QEMU/OP-TEE instances (debugging, multi-user etc.) on the same physical (non-containerized environment) computer, this is useful because you can avoid port collisions (port already in use message) by simply setting non-clashing port numbers when running make and thereby also avoid making changes directly to the makefile.
